I might be able to even get rid of the distinction between pages and templates. Templates are just a final transformation step, exactly the same as calling ´site.process´ and having it, say, turn Markdown files into HTML.
I was thinking about how to solve support for Vue templates since these turn a single page into multiple files, including SCSS. And then how would I compile the SCSS if templates are the final step? Removing this distinction would make it possible since there can be any kind of processing afterwards.
